Ecom Express — Item has reached delivery centre but agents are not delivering

Address:

No. 14/12/2, Samalka,Old Delhi-Gurgaon Road New Delhi New Delhi District Delhi India - 110037

I have ordered a mobile phone via MI store and it is being delivered through Ecom.It has been 10 days since the order has been done .The order reached the delivery centre 3 days ago and the delivery agents have not shown up till now, .Today i went to the delivery office and enquired about the order, they said since they dont have delivery boys they have returned the item back.How irresponsible is this.They could have given a call on this, they just returned the item.I called up the customer care and the executive is least bothered and is not even registering the complaint.She said her supervisor will contact me in 2 hours and it has been 4 hours and no one has called. The item is still in delivery centre says the customer care executive. I am willing to go and take the order from the agent.Fix this issue asap.
